Hi Dave,
I suspected after initial testing a problem in TTY and applied two patches. After more testing the root cause was a problem in JBD2. A patch from Eric helped! Follow the thread in [1] for more details.
If you are on Linux-Next (next-20130118) you need the following three patches.
Ilya Zykov (2): tty: Correct tty buffer flush. tty: Add driver unthrottle in ioctl(...,TCFLSH,..).
Eric Sandeen (1): jbd2: don't wake kjournald unnecessarily
Hope this helps you.
Regards, - Sedat -
